Resumo: | The blast is the main disease of flooded rice. The integrated management of this disease is based on the adoption of cultural, genetic and chemical strategies of control. The objective of this work was to evaluate the effect of eight chemical control programs of Pyricularia oryzae applied on IRGA 424, IRGA 428, GURI INTA CL, PUITA INTA CL, QM 10 10 CL and INOV CL rice varieties, and 10/30/2013 and 11/26/2013 sowing times. This work was conducted in the 2013/2014-crop season, under field conditions, in lowland area in Sao Sepé, RS, Brazil. The treatments were arranged in a randomized experimental blocks design, in a split plot and five replications. The variables analyzed were AUCPD on the flag leaf and entire plant, panicle blast, yield and the whole grains percentage. The delay in sowing date increased significantly the incidence and severity of the blast in flooded rice. IRGA 424, IRGA 428 and QM 10 10 CL showed resistance to Pyricularia oryzae, while the GURI INTA CL, PUITA INTA CL and INOV CL were susceptible. The addition of Tricyclazole fungicide to Kresoxim-methyl + Epoxiconazole fungicides is critical to the efficient control of Pyricularia oryzae. The applications of fungicides in the R1 + R2 + R4 and R2 + R4 stages are the most effective in the chemical control of rice blast. The integration among cultural, genetic and chemical methods is critical to the efficient management of blast in flooded rice. |

O manejo integrado desta doença é baseado na adoção de um conjunto de métodos de controle, como o controle cultural, controle genético e o controle químico. O objetivo deste trabalho foi avaliar o efeito de oito programas de controle químico de Pyricularia oryzae, nas cultivares de arroz irrigado IRGA 424, IRGA 428, GURI INTA CL, PUITÁ INTA CL, QM 10 10 CL e INOV CL, nas datas de semeadura de 30/10/2013 e 26/11/2013. O experimento foi conduzido em São Sepé/RS, na safra 2013/14, obedecendo o delineamento experimental de blocos ao acaso, em parcelas subsubdivididas e cinco repetições. As variáveis consideradas foram AACPB na folha bandeira e na planta inteira da cultura do arroz, o percentual de incidência de brusone na base da panícula, a produtividade e o percentual de grãos inteiros. O atraso na época de semeadura aumentou significativamente a incidência e a severidade da brusone na cultura do arroz irrigado. IRGA 424, IRGA 428 e QM 10 10 CL apresentaram resistência à Pyricularia oryzae, enquanto que GURI INTA CL, PUITÀ INTA CL e INOV CL foram suscetíveis. A adição do fungicida Triciclazol aos fungicidas Cresoxim-metilico + Epoxiconazol foi eficiente para controle de Pyricularia oryzae. As aplicações de fungicidas para controle químico da brusone foram mais eficazes quando realizadas nos estádios R1 + R2 + R4 e R2 + R4. A integração entre os métodos cultural, genético e químico foi eficiente para o manejo da brusone na cultura do arroz irrigado.application/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em AgronomiaUFSMBRAgronomiaOryza sativaPyricularia oryzaeControle culturalResistência genéticaControle químicoOryza sativaPyricularia oryzaeCultural controlGenetic resistanceChemical controlCNPQ::CIENCIAS AGRARIAS::AGRONOMIAÉpocas de semeadura, genótipos e programas de controle químico no manejo integrado da brusone na cultura do arroz irrigadoSowing times, genotypes and chemical control program in the integrated management of blast in flooded riceinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisBalardin, Ricardo Silveirohttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4721447T7Madalosso, Marcelo Gripahttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4778101E2Debortoli, Monica Paulahttp://buscatextual.cnpq.br/buscatextual/visualizacv.do?id=K4770905J5http://lattes.cnpq.br/1139896538047703Pinto, Felipe Frigo500100000009400500300300300db30a6fa-b8fd-467f-8b97-06372e631430e8c174a7-af69-4a31-bac0-74ddb9b1d53664f9dea9-deae-4fb1-9c57-5fb56517f9b80059532f-7c0d-4435-88c4-f30bb031bb06info:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALPINTO, FELIPE FRIGO.pdfapplication/pdf1623236http://repositorio.ufsm.br/bitstream/1/5153/1/PINTO%2c%20FELIPE%20FRIGO.pdf9673aa772b22727b950e8a935ceee928MD51TEXTPINTO, FELIPE FRIGO.pdf.txtPINTO, FELIPE FRIGO.pdf.txtExtracted texttext/plain99587http://repositorio.ufsm.br/bitstream/1/5153/2/PINTO%2c%20FELIPE%20FRIGO.pdf.txtf2dd86e9210cf29d5e8595476cf95ab7MD52THUMBNAILPINTO, FELIPE FRIGO.pdf.jpgPINTO, FELIPE FRIGO.pdf.jpgIM Thumbnailimage/jpeg4751http://repositorio.ufsm.br/bitstream/1/5153/3/PINTO%2c%20FELIPE%20FRIGO.pdf.jpg63904dc3d51fe6a8f9e0f63450c2cb96MD531/51532017-07-25 11:13:13.403oai:repositorio.ufsm.br:1/5153Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2017-07-25T14:13:13Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |

The blast is the main disease of flooded rice. The integrated management of this disease is based on the adoption of cultural, genetic and chemical strategies of control. The objective of this work was to evaluate the effect of eight chemical control programs of Pyricularia oryzae applied on IRGA 424, IRGA 428, GURI INTA CL, PUITA INTA CL, QM 10 10 CL and INOV CL rice varieties, and 10/30/2013 and 11/26/2013 sowing times. This work was conducted in the 2013/2014-crop season, under field conditions, in lowland area in Sao Sepé, RS, Brazil. The treatments were arranged in a randomized experimental blocks design, in a split plot and five replications. The variables analyzed were AUCPD on the flag leaf and entire plant, panicle blast, yield and the whole grains percentage. The delay in sowing date increased significantly the incidence and severity of the blast in flooded rice. IRGA 424, IRGA 428 and QM 10 10 CL showed resistance to Pyricularia oryzae, while the GURI INTA CL, PUITA INTA CL and INOV CL were susceptible. The addition of Tricyclazole fungicide to Kresoxim-methyl + Epoxiconazole fungicides is critical to the efficient control of Pyricularia oryzae. The applications of fungicides in the R1 + R2 + R4 and R2 + R4 stages are the most effective in the chemical control of rice blast. The integration among cultural, genetic and chemical methods is critical to the efficient management of blast in flooded rice. |
